Title: Moving device on wall
Inventor: NAKAHARA HIROTAKA
IPC: B62D57/024
Filed: 1993-03-15
Abstract: PURPOSE:To stably move against a wall having the surface of optional inclination or curvature by providing a bellows supporting a suction cup and having a vacuum forming chamber independently of the suction cup, the vacuum forming mechanism of the bellows, and the supporting part of the bellows, and enabling the oscillating rigidity of the suction cup to change. CONSTITUTION:A vacuum type suction cup 1 is supported with a bellow 2 which can loosen or contract, and the bellows is supported with a supporting part 3. When the suction cup 1 approaches a face to be sucked 0, the vacuum forming chamber of the suction cup 1 is released to the atmosphere, and the vacuum forming chamber of the bellows 2 is evacuated so as to contract the belows 2. As a result of this, the recessed/projecting parts of a fitting mechanism 5 between the suction cup 1 and the supporting part 3 are mutually fitted together so as to improve oscillating rigidity of the sucking device, and when the suction cup is contacted with the face 0, the vacuum forming chamber of the bellows 2 is released to the atmosphere so as to loosen the bellows by an antenna sensor 4. Next the recessed/projecting parts of the fitting mechanism are separated so as to lower rigidity, and hence the suction cup is smoothly contacted with even the face 0 having curvature or innclination.

Abstract: PURPOSE:To improve the output by shaping a pushing part of a tapper to a valve stem to change the contact position between a cam face of cam shaft and a pressure-receiving part of the tappet on the basis of the rotation of a rotational member round the cam shaft into a curved surface of a fixed curvature for enabling to extend a valve opening time. CONSTITUTION:When a reciprocating shaft 18 is moved to the right by a driving unit, a rotating member 14 is oscillated round a cam shaft 9. The contact position between the cam face 9a and a tappet pressure-receiving part 13a is changed to the delay side against a cam rotating direction X, and the valve timing of a suction (exhaust) valve 5 is slided in a delay direction. As for a pushing part 13b of the tappet 13 to push down a vlave stem 5s of the suction valve 5 when a pushing force of a cam face 9b works, the contacting face with the valve stem 5s is shaped into a curved face with less curvature than the one having a curvature radius around a center of a rotating member 14 at a position where the tappet 13 is not pushed down by the cam face 9b.

IPC: H05K3/00
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To form a metallizing surface having a strong adhesive force by coating an initial circuit layer on a board with a photoresist, surface roughing the photoresist, then adsorbing a palladium ligand to a photoresist sidewall for forming the photoresist and a via opening, and catalyzing the exposed ligand layer with a specific catalyst. SOLUTION: An initial circuit having an insulator board 10 and a metal land 11 is formed. The top surface of a photoresist layer 13 provided with a via opening and a sidewall for forming the via opening are roughened to form a surface 14. At the sametime, a palladium ligand 15 is adsorbed to a protrusion and recess part of the sidewall of the layer 13 for forming the top surface and the via opening. The exposed surface is catalyzed by using, for example, PdBr selective catalyst, reduced to Pd, and a pad 17 is formed by electroless metal precipitation on the exposed surface, such as, for example copper metal precipitation. Thus, a metallized surface having strong adhesivity degree can be formed.

Abstract: PURPOSE:To perform high-precise arcuate interpolation responding to an object work by providing a means to fetch an arcuate type from an arcuate interpolation command and a means to select the terminal end position of an arc of a circle responding to the fetched arcuate type. CONSTITUTION:An arcuate interpolation command previously taught by a user is stored in a work program memory part 1, and a command is fetched by a command fetching part 2. Further, when an arcuate interpolation command is taught, a user selects an arcuate type ac cording to the shape of an object work. Since, during an arcuate interpolation command, a command.arcuate position.arcuate type is not stored in an output from the command fetching part 2, types are stored in respective memory parts through decision of an arcuate interpolation command interpreting part 3. An arcuate type is fetched by a fetching part 20, and the object position of arcuate interpolation is decided by an arcuate type deciding part 21. When the arcuate type is A, P2 is stored in an arcuate object position memory part from an arcuate position memory part by means of an arcuate object position generating part 22.

Filed: 1992-03-13
Abstract: PURPOSE:To surely identify the respective pipes of the pipe cable internally having the plural pipes for transporting an optical fiber unit by using a compressed gas. CONSTITUTION:The pipes 2 for transporting the optical fiber units are required to constitute at least identifying bodies not to constitute the inside surfaces of the pipes. For example, a colored layer 2-2 is applied on the outer layer of each pipe or a mark 2-4 is applied on the outside surface of a non-colored layer 2-1 to prevent the deposition of colored pigments on the inside surfaces of the pipes in which the optical fiber units pass. The identification of the pipes is thus assured while the performance to forcibly feed the optical fiber units is maintained.

CONSTITUTION:An automatic addition apparatus 10 used to add ammonia water 9 by means of a dosing pump 8 at intervals of a definite time is formed in such a way that a timer 6 is built in. Water which has been weighed in a weighing tank 5c is first transferred to a treatment tank 1; after that, it is heated up to a treatment temperature of about 70 deg.C by means of a heater 27 after that, ammonia water and hydrogen peroxide water which have been weighed in weighing tanks 5a, 5b are mixed; a cleaning chemical liquid is prepared. The cleaning chemical liquid is circulated through a pump 3 and a filter 4, and a cleaning operation is performed while particles in the chemical liquid are being removed. After the chemical liquid has been mixed once, it is not required to add and supply hydrogen peroxide. Although ammonia depends on a treatment temperature, it is detected that the concentration of the cleaning liquid can be kept definite by adding a chemical liquid in a definite quantity at intervals of a definite time. Thereby, the concentration of the chemical liquid is controlled simply and an etching rate and a cleaning effect can be kept definite.

Abstract: PURPOSE:To inhibit a diffused junction capacitance between source-drain and a substrate at a small value by implanting ions in order to increase substrate concentration while counter-doping ions so that only an ion implanting layer under a gate region is left. CONSTITUTION:Oxide films (SiO2) 12 having trench structure deeply penetrating in the vertical direction in the surface of a substrate 11 are formed to the substrate 11 in order to isolate each element.
